To all whom it may concern:

Be it known that I, LOUIS a citizen of the United States, residing at Jenln'ntown, in the county of Montgomery and State of Pennsylvania, have invented certain new andfuseful Improvements in Portable Batteries, of which the following is a specification.

The principal object of the present invention is to provide a portable battery which can be placed in .any position, even up-sidedown, without danger of leakage and with proper ventilation while at the same time the plate space may be filled so as to increase the capacity without substantial increase in height or outside dimensions.

The invention W111 be claimed at the ad Fig. 3, showing a part of the battery, and' Fig. 5, is a similar view takenon the line 55, of Fig. 3.

. The cell is sub-divided by partitions 1, extending from the top to. the bottom thereofinto a plate space 2, and gas space 3, and

chambers a and b. The cell is provided with ventilation tubes or passages 4 and 5, communicating with the air, as through the vent openings. 6, of plugs 7, and extending into the middle portions of the chambers a and b. In the cover 8, are oppositely disposed vent tubes or passages 9- and 10, one

of which opensto the gas space 3, adjacent to one corner and extends and opens into the ventilation chamber 6, near the end thereof and whereof the other opens to the gas space 3, atoradjacent to the diagonally opposite corner and'extends and opens into the other ventilation chamber a, near the end thereof. The portions of the vent tubes orpassages 9 and 10, adjacent the cover 8,- are inclined'from their communication with H. FLANDERS,

that no liquid will escape. 'be turned on its side the liquid level will the gas space away from the interior of the cell to provide for drainage. Evidently the plate structure 11, is substantially as high leaving but a small gas space above commensurate in size with the space left in ordinary batteries. In this. Way the capacity of the battery is relatively large in'proport 1on to its size considered as a portable battery- The ventilation chambers a and 6, do

not add to the height of the battery and they add very little to its other dimensions slnce portable batteries are frequently rounded so as to fit other appliances or for other reasons. To take an extreme case, if the battery is turned up-side-down the level of the electrolyte will be below the upper ends of the tubes or passages 9 and 10, so If the battery fill that portion of one of the tubes 9 and 10, that is adjacent to the cover but will not reach the other-tube or passage, so that the latterremains effective for ventilation by way of the ventilation chamber with which it communicates. If in course of time the fluid reaches the ventilation chambers a and b, it may not readily escape therefrom through the openings 6, because the tubes or passages 4 and 5, project-well into those as the cell so that the plate space is large chambers and project above the level of the liquid therein even when the battery is turned up-side-down. If, however, an excess of liquid collects in the chambers a or b, considerable time would be required and at the end of that time it can be drained ofi by the removal of the plugs 7 J The result of the improvement is that the battery can be violently shaken and turned into any position that it would'naturally get into in the course of its juse'l without spilling liquid.

' For instance, the battery can be used by miners and carried on their'ba cks without spilling liquid. Whenthebattery is inupright position, it is ventilated by way of the passages 9 and 10, the chambers a and b,

and tubes 4 and 5, and asit is inclined from- .sets of tubes remains operative.

What I-claim is: j 'A storage battery cell sub-divided into that position either oneor the other ofthe plate and gas spaces andchambers provided with ventilation tubes or passages communieating with the air and opening and extending into the middle portions of the chamhers, and having in its cover oppositely dis- 5 posed vent tubes or passages one of which opens to the gas space of the cell at or adjacent to one corner and extends and opens into one chamber near the end thereof and whereof the other opens to the gas space of the cell at or adjacent to the diagonally op- 10 posite corner and extends and opens into the other chamber near the end. thereof, substantially as described.
